BOOK-MARK.

SPECIFICATION forming part of Letters Patent No 759,427, dated May 10, 1904.

Application filed May 14, 1903. Serial No. 157,028. (No model.)

To all whom it may concern:

Be it known that I, HARRY C. FAIRoHILD, a citizen of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented a new and useful Book- Mark, of which the following is aspecifioation.

My invention relates to a book mark by.

means of which, in addition to the customary uses of a book-mark, references to page and line can be speedily and accurately turned to, consecutively or in any order desired, thus doing away with the use of separate ribbons or slips of paper, and is especially adapted to Biblical study or scientific books. I accomplish these objects by the device illustrated in the accompanying drawings, in which similar letters are used torefer to similar parts throughout.

Figure 1 is a View of my book-mark applied. Fig. 2 is a face view of my book-mark. Fig. 3 is a longitudinal section of my bookmark. Fig. 4 is a detail view of the indicating-arm O.

My book-mark,which is made preferably of celluloid, consists of two standards B B and an indicating-arm C. The standards B B, which I designate as outer and under standards, are held together at their tops by a rivet c or some similar means and are adapted to be detachably connected at their bottoms by means of the tapered end I) of the outer standard Bthrust through a circular opening Z) in the under standard B.

The indicating-arm C is arranged at one end to slide upon the outer standard B by means of the cuttings 0, the indicating-arm thus extending from left to right at a right angle to the outer standard B and is made slightly longer than the width of the page of the book in which it is used.

In operation the indicating-arm C is passed over the outer standard B by means of the cutting a, the arm extending from left to right. The leaf of the book is passed between the outer and under standards, the standards then being connected at their bottoms by thrusting the point 6 through the circular opening b.

here the book-mark is used to show a number of references, a separate book-mark is used for each reference, the indicating-arm of each book-mark having at its outer end a number indicative of the desired reference, Fig. 1. verse or line, the user simply marks upon the outer standard B with a lead-pencil, as shown by d 01, these marks subsequently being rubbed out or erased, and for this reason celluloid or some similar substance is used in the construction of the book-mark.

Having fully described my invention, what I claim, and desire to protect by Letters Patent, 1s

A book-mark comprising an outer and an under standard joined together at their tops and detachably connected at their bottoms, and an indicating-arm arranged at one of its ends to slide upon the outer standard, and extending at a right angle therefrom, substantially as set forth. In testimony whereof I, HARRY C. FAIR- CHILD, have signed my name to this specification, in the presence of two subscribing witnesses, this 12th day of May, 1903.
